PC4711-W
Single-Phase WiFi Open API Smart Energy Meter
UniClip Open on WiFi only: single-phase metering straight to your own cloud over HTTP, MQTT or Modbus TCP, with no app and no vendor cloud.
Overview
PC4711-W (UniClip Open) is the Wi-Fi member of the Open API range: a single-phase meter that reports to your infrastructure rather than a vendor cloud, over HTTP, MQTT and Modbus TCP, with no app and no cloud account.
Two things change compared with the Tuya models: the data path, with nothing between the meter and your server, and the reporting interval, which is a parameter of your integration rather than a platform decision - on top of a 50 ms data refresh. If the platform side is a wired bus, take PC4711-W-485 instead.
PC4711-W Platform and Integration Notes
The reporting interval is yours to set, in your integration, on top of a 50 ms data refresh — no platform decides it for you.
Up to two open-type CTs, 80 A to 300 A, clipped around the existing conductors without rewiring. Voltage is measured to ±1%, current to ±1% at rated and ±2% at low current.
Full remote management. OTA firmware, CT configuration, data erase and remote reboot are all reachable over the network.
Bidirectional metering. Consumption and solar production on the same single-phase circuit are both recorded.
PC4711-W Limits and What to Specify Instead
- RS485 / Modbus RTU — not fitted. The PC4711-W-485 adds the serial bus and keeps the Wi-Fi path.
- Three-phase supplies — the Open API equivalents are the PC4713-W and PC4713-W-485; a 3P3W or delta service needs the Tuya-series PC4713-W-E-TY/3W.
- Relay output — no model in the Open API range carries a dry contact.
- The Tuya App and Tuya Cloud history — this meter reports to your infrastructure instead.

Key Benefits
Your Data Stays Yours
HTTP, MQTT or Modbus TCP straight to your own cloud or local server, with no third-party cloud in the path.
No App and No Account
The meter serves its own configuration page over its hotspot — nothing to install on a customer phone.
Four-Quadrant With Demand
Switchable RMS / PQS modes plus current and maximum demand, for import, export and reactive analysis.
Minute-Level Offline Storage
Buffered locally at minute intervals and re-reported after a reconnect, so a dropout does not become a hole in the dataset.
Ideal For
Common deployment scenarios where Single-Phase WiFi Open API Smart Energy Meter delivers the most value.
Single-Phase Solar and Storage
Reporting into an operator own platform over HTTP, MQTT or Modbus TCP.
Tenant Billing on Own Infrastructure
Data stays on the customer systems rather than a third-party cloud.
Home Assistant and Self-Hosted Dashboards
The meter is configured in a browser and feeds a local system directly.
Anti-Backflow on a Single Phase
50 ms data refresh and a reporting interval set by the integration.
EV Charging Submetering
Four-quadrant measurement with current and maximum demand.
Distributor and OEM Programmes
Neutral standard units, with branding and packaging available.
